I '0 all av/10m. it may concern 1 Be it known that I, PHILIP C. Msimnn,United States, residing at in the county of Linn and have invented a newand Means for- Car Dooi-s, &c.,

specification.

The invention-relates to improvements in fastenin means for car doors,etc.

The 0 ject of the present invention is to improve the construction offastening means for car doors, etc.,more especially the means forsecuring the car door,'.shown and described in an application filed byme on or about Oct. 19, 1912, Serial No. 726,753, when acar is to beloaded with grain.

' A further object of the-invention is to provide locking means adaptedto securely hold the lower portions of the sections of the car door attheir free or. mceting edges Cedar Rapids, State of Iowa, usefulFastening ing' forced apart, whereby the car door is rendered perfectlygrain tight at the bottom. It is also the object of the invention to .95provide locking means of this character adapted to receive acar seal, sothat the bottom locking means cannot be unfastened without plainlydisclosing the fact that it has been tampered with.

'80. With these and other objects in View, the

invention consists. in the construction and novel combination of partshereinafter fully described, illustrated in the accompauving drawings,and pointed out in the .claims beneto appended; it beingunderstood thatvarious changes in the form. proportion. size and minor details ofconstruction. within the scope of the claims, may be resorted to withoutdeparting from the spiritv or sacrificing anvof the advantages of theinvention.

11 the drawings Figure 1 is a front elevation of a. portion of a graindoor provided with fastening means. constructed in accordance. with thisinvention. Fig. 2 is a front elevation of the pivoted locking device.Fig. 3 is a. vertical sectional view of the same. Fig. 4 is a horizontalsectional view of the pivoted locking device.

Fig. ,5 is a detail perspective view of the locking, arm.

plan view, partly in -sec-. which secures one end of the exterior doorfastening chain Like numerals of reference designate corresponding partsin all the figures of the I Tin-am the invention, the car door isconstructed substantially the same as-that shown and I described in theaforesaid application, the

trated. The door sections and 3 are hinged together and the doorsections 4 and 5 are likewise hinged together forming two sectionaldoors. I slidabl'y connected with vertical pintle rods 8 by hingeelements, composed of two leaves 9 and .10 hinged together by a verticalpintlc located at opposite sides of the door opening of the car. aresupported at intervals by fixed-hinge elements or brackets 13, providcdwith vertically the pintle rods 8 and having horizontal slots 14 throughwhich pass bolts 15, or other hinge elements or brackets 13 in fixedadjustment.

No claim is made in the present applicawhich form the subject-matter ofa eopending application. filed Oct. 19. 1912. Serial No. 726.753.Neither is any claim made in the'prescnt case to the device for attachtotbe bottom orfloor of the car.

The vertical door section 4 is held against outward movement by apivot-ed lockingde vice comprising a locking arm 41 located atthe innerface of the door 4 and provided with an integral pivot 42. extendingoutwardly tl'irough the door section 4 and through a bearing opening43in a plate or support '44. which is secured. to the outer face of thedoor section 4. The locking arm. which is of a length to project beyondthe free edge of-the vertical door section 4 and extend over or overlapthe adiacent portion of the vertical door I slightly from the-inner faceof the door section 4 by an annular boss 45. surrounding I the inner endof the pivot and being of athickness slightly in excess of the thicknessof the door section 4- and fitting against the trated in 10 of thedrawings. 'The spacing of .the locking arm from the inner faceof thedoor 4 prevents the locking arm from binding andenables the same toswing The door sections 2 and?) are 11. The verticalpintle rods 8, whichare" alined eyes to receive suitable fastening means for securing the'tion to the long and short inclined chains.v

ing the. lower end of the long inclined chainsection 3, is spaced v to.and from its engaging position.

is illustrated the preferred embodiment of upper door thereof beingomitted and only portions of the vertical door sections 2, 3, 4 and 5 ofthe lower or main door being illusinner face of the plate 44, as clearlyillus I The plate or support 44 is secured to the outer face of the doorsection t byaipper and lower bol'ts trand 47, and the nut 4:8'of thelower bolt is arranged to be engaged by a projection 49 ot' the lockingarm and forms astop for the same and supports the locking arm in itsengaging position, and the locking arm is also adapted when swungupwardly-aiul rearwartlly out of engagement l nstably connected with akeeperconsisting with the door section 3 to rest upon and be supportedby the nut of the said fastening device.

The pivot- 4-2 is secured in the bearing opening 43 ot' the plate orsupport by a cotter pin 49 piercing the pivot and arranged at the outerace of the plate or support 44 and ha ring its head located'beneath theupper portion of an arcnate guard'fiange 50 when the locking arm is inits engaging po sition. "The guard flange .70, which is formed integralwith the plate or support. is spaced'fi'om the head of the-cotter pinand extends downwardly a distance greater than the arcuate movement ofthe head of the cotter pin in the pivotal movement of the looking arm inswinging to andfrom its engag- By. this construction the cotingposition. ter pin is effectually prevented from being removed when theparts are assembled and seeured tothe car door. The'parts are assemblefdbZiitire the lower bolt is applied to the plate or support, and when thelatter is removed, it will permit the free swinging movement of thelocking arm and will enable the head of the cotter pin to be carriedbeyond the guard flange. so that the said cotter pin may be readilyremoved if desired. Any other form of detachable stop may, of course. beemployed for limiting the movement of the locking arm' to retain thehead of the cotter pin normally between the terminal portions of theguard flange.

The outer portion 51 of the pivot is reduced and provided with flat sidefaces to form -a wrench receiving portion, and it has a :lot oropening52 adapted to receive a wire 53 of a. t-ar seal 54. The wire of the carseal is also missed through a slot or opening in the lower eudof avertically mov able boll 5'6. consisting of a rounded lower portion andan enlarged upper portion provided with-a longitudinal slot 57 throughwhich passes a rivet 58. projecting from a hollow stud 5S) and'gnidingthe upper portion of the slidable 'bolt. The upper slotted portion ofthe bolt fits against the outer end of the stud 59, and it is groovedat:

its outer face at opposite sides of the slot 57 The to receive the headof the rivet 58. lower rounded portion of the bolt 56 is guided in anopening ('30 of an arm 61, formed integral with the plate or support andextending horizontally from the same and located beneath and in verticalalinement with the hollow stud 59-. The bolt 56,.

grasped, is adapted to be lifted above-the horizontal arm 61, whichreceives a llnk of a I shortchain (33, adapted to be retained on the arm61 by the bolt. lVhen the slidable bolt is lifted out of engagement withthe chain receiving arm, 1t 1s free to swing on the rivet 58. The otherend of the chain is adof a horizontal handle 64: having terminalattaching portions 65 and an outwardly ex-' tending approximatelyU-shaped intermediate portion, which is provided at its inner face withan L-shaped lug 66, forming a gage a link of the chain 63. The chain isfirst placed on the hook-shaped lug 66 and is retained in engagementwith the same by the horizontal arm 61 after being placed thereon. T he.chain is confined on the arm gaging position, and it will be seen thatin order to unfasten the lower ortions of the vertical door sections 3an 4:, it will be necessary to break the wire of theseal. This may bedone by rotating the pivot with a wrench, or other suitable tool;
